The final decision rests with the TSA officer.
A more truthful and accurate way of stating it would be: "Nothing is allowed unless a screener says it is".

In actuality, TSA allows nothing. Using “screener discretion" TSA can confiscate ANYTHING no matter what’s on a list or what @AskTSA says is o.k.
